CVE-2025-29910

CryptoLib's crypto_handle_incrementing_nontransmitted_counter Function has Memory Leak

Published Mar 17, 2025 CVSS 4.0 · 5.5 Medium EPSS < 1% KEV · Not listed
Description
CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. A memory leak vulnerability was identified in the `crypto_handle_incrementing_nontransmitted_counter` function of CryptoLib versions 1.3.3 and prior. This vulnerability can lead to resource exhaustion and degraded system performance over time, particularly in long-running processes or systems processing large volumes of data. The vulnerability is present in the `crypto_handle_incrementing_nontransmitted_counter` function within `crypto_tc.c`. The function allocates memory using `malloc` without ensuring the allocated memory is always freed. This issue can lead to resource exhaustion, reduced system performance, and potentially a Denial of Service (DoS) in environments where CryptoLib is used in long-running processes or with large volumes of data. Any system using CryptoLib, especially those handling high-throughput or continuous data streams, could be impacted. As of time of publication, no known patched versions are available.
